Rewrite the following content into a 2000-word, SEO-optimized article in English. Write it in the style of a professional journalist or news reporter. The article should be fully humanized, natural, and engaging — not robotic or repetitive.
Focus on clarity, flow, and storytelling while preserving the meaning of the original. Structure the article into 6 well-developed paragraphs with smooth transitions, strong headlines, and a professional tone. Use varied vocabulary, sentence lengths, and natural phrasing to make it read like human-written journalism.
Avoid keyword stuffing, but naturally integrate important SEO keywords throughout the article. Ensure the final article feels like it was written by a skilled reporter for a reputable news outlet.
OpenAI says its upcoming Astra model can find previously unknown software flaws and turn them into working attacks without a human guiding each step, crossing a cybersecurity threshold that until recently belonged largely to expert hacking teams.
It is the first model OpenAI has classified as having “Critical” cyber capabilities under its Preparedness Framework, the firm wrote in a Tuesday post.
To qualify, a model must be able to find previously unknown software flaws, known as zero-days, and develop working exploits for them across hardened real-world systems without human intervention, or devise and execute an attack from little more than a high-level goal.
In testing, Astra scored 100% on a benchmark for developing exploits from known vulnerabilities and found two previously unknown flaws while building an exploit chain on a separate internal test.
It also broke out of a hardened browser sandbox and executed commands on the host computer, while separately finding and combining multiple flaws in an operating system to gain root access, OpenAI said.
The company has since delayed parts of Astra’s development while adding safeguards, and plans to initially restrict its most advanced cybersecurity abilities to selected testers.
